Poor funeral cover department response

Worst!!!have called from last week to ask to change the beneficiaries on my funeral cover. You get rerouted to client service. They tell you that all agents are busy and someone will call. It is now the 7the day that I am being told the same thing. No one gets back to me. Please call me so that I can change my beneficiaries please. And stop this thing of taking our details when you know that no one will call back. I rather wait in the queue for long and be assisted that get quick answer but not get help.
